Title: O-Methyl-isourea sulphate prodn. - from cyanamide methanol and sulphuric acid with controlled temps and molar ratios
Inventor: WEISS STEFAN DR
IPC: C07C273/00
Filed: 1974-08-10
Abstract: 31-41 pts. wt. of solid cyanamide is added at -10 to +20 degrees C to a stirred, cooled soln. of 50-150 pts. wt. methanol and 100 pts. wt. of conc. sulphuric acid. The product O-methyl isourea bisulphate (I), opt. isolated as the crude prod. impregnated with methanol is reacted with an almost stoichiometric quantity of cyanamide in 50-160 pts. wt. of methanol at +5 to +40 degrees C for 4-72 hrs. to give O-methyl isourea sulphate (II). (I) and (II) are important intermediates which react with amines to form guanidines (e.g. 1,17-biguanidino-9-azaheptadecane sesquisulphate is a fungicide used for disinfection of seeds) or may be used as methylation agents. (II) may be used as guanylation agent for 1,8-diguanidinooctane and 1,10-diguanidinodecane fungicides used against rice smut. The known process for preparation of (II) from cyanamide, methanol and sulphuric acid is a single stage process which takes 4 days and gives yields of about 44% and is unsuitable for industrial scale production. The present process gives almost double the yield in shorter reaction time.

Title: Purification unit for cooker fumes and vapours etc - has off-set filters and deflector reducing risk of fire when removing grease
Inventor: MASSART ANDRE
IPC: F24C15/20
Filed: 1974-09-19
Abstract: The gases, vapours, smoke etc. from the cookr or hearth rise up and are deflected by the deflector to and through a non-inflammable e.g. metal filter which separates the glowing particles entrained by the vapours. The gas etc. are then drawn up through the degreasing filter which is offset relative to the first filter so that degreasing is carried out away from the flames and heat of the cooker thus reducing the risk of fire. The temp. of the gases is reduced to below 100 deg.C before they reach the final filter by extending the time in which the gases etc. contact the walls of the filter device which is kept at a farily low temp. since it is automatically cooled by the atmosphere. In the case of a charcoal fire, a further plate can be added just above the burning hearth to remove the solid particles.
